how do u go about clocking that and how much more cooling would i need? i just purchases a ASPIRE X-Gear ATXB5KLW-BL/350 Blue Steel ATX Mid Tower Computer Case what more do i need?
Take the card up in small steps. Maybe 5mhz or so, less if you like. Run 3dMark and some games jus to make sure things are still stable. And if it doesn't have any active cooling (read: fan) then put some on it.
